Abstract

The compounds of the general formula I are of interest, in particular, as chemical aroma substances, but were hitherto not easily obtainable. To prepare these compounds, according to the invention, a compound of the formula II is reacted with an isoolefin of the formula III in the presence of a disproportionation catalyst. The symbols used in the formulae are defined in Claim 1. <IMAGE>
